DUST COLLECTOR;

Application ined February 17, 192e.y seriai No. 88,815.

My invention relates to dust collectors such as are adapted to be used particularly 1n shoe repair ornishing machinery in which one or more sanding` and scouring wheels are used, each of which is usually provided with a chute connection to a blower which carries the dust from the wheels to a discharge point.

The dust produced by the machine is freqiiently discharged outside of the building but this is not always practical, and itis desirable to use a `dust collector by means of which the dust may be removed "from an air stream passing therethrough and the air'discharged into the operating room,

rlhe general object ot my invention is to provide an etheient collectorior the purpose mentioned, and the detail objects of my invention are to provide a coliector which may be mounted on the ordinary finishing inacliine, which will include an easily filled and cleaned water chamber through which air may be passed, and which may be connected at either end to the blower `according' to the relative location ot the blower and dust collector. y n

In the accompanying drawings. which illustrate a preferred embodiment ofmy iny vention,-

Figure 1 is an elevationof a finishing machine and viewing the same from the. front ot the finishing machine with my collector shown thereon in longitudinal section.

Figure 2 is a vertical cross section through 'my dust collector, talren on line 2-2 of Figure 1 and showing the adjacent parts of the finisher frame.

rlflie upright trames of the finisher are indicated at 1 and they areV connected'by 'the inisher framing. The trame mounts the operating shaft 4 which is located a sliort distance above lowerV trame elements 2. ing shalt 5. All of the above-mentioned parts are ot ordinary construction and form no part of my invention.V l The dust collector is of box-like structure and comprises front and back walls G and a bottom walllO. rthe bottom wall is olif- Ypression so that any water in the rear por- 7, respectively, end walls 8, a top wall 9, andv tion of the collector will drain into the depression. The end walls G and 7 are provided with suitable openings through .which an intake pipe 12 may pass, pipe 12 being` open at both ends with each end adapted `to have a cap 13 applied thereto or to be connected to a blower 14 by means of ank elbow 15 or the like.

The lower portion of pipe 12 is provided with an opening to receive a downwardly extending conduit 16, the lower endl of which projects-below the top ot' the water chamber forming depression .11 in the ffront of the box. The conduit is inclined forwardly somewhat to bring its mouth inthe center of thewater chamber.

Behind pipe 12 'I provide a longitudinal upright baffle 17 lshown as extending from end to end of the collector and having its lower edge spaced a short distance above the bottom wall 10` to permit drainage thereunder. lThe upper edge of the baffle Vis spaced a substantial distance from the top ot' the box and is provided with a horizontally forwardly extending` fiange 18 terminating in a return bend 19.

Behind and spaced from battle 17 I provide a-second baiiie 2O extending downwardly from the top of the boX and having a lower flange 21 with 'a return bend 22. Behind'baffle 2O the top of the collector is provided with an opening to permit the discharge of air passed through the device. Air forced into the collector through pipe 12 passes downwardly through the water in depression-11 and then upwardly over baffle 17 and then downwardly under baliie 20 and horizontal pipes 2 and 8 forming` parts of The iframe also Ymounts the wheel carry-Y of depression 11 is inclined toward the de-l then upwardly into the' room. The tortuous passage provided for theair and the flanges on the bai'iies are adapted tointercept and collect any `drops-of water which would otherwise be likely to be carried through the device b-y the air stream.

The depressed portion of the collector forming the water chamber is provided with Va drain plug 23 and an overliow plug 24: and vthe top oi the collector is'provided with a removable cover 25. These elements vrender it easyfor the ordinary workman using the finishing machine to empty and refill the water chamber when desired. Y

The offset bottom of the collector, besides providing the water chamber, adapts the device for clearing the operating shaft 4f. The collectorv may be supported by suitable U- shaped straps 26 on the upper `frame ele,-

ments 3. The bottom olil the collector is inclined from the drain plug and upwardly toward the opposite end t-o facilitate cleaning of the device. y

I direct attention to the fact that the sectional areas of the conduit 16 and of the passage from the conduit and around the sides of the same and to the discharge opening and the area oit the latter are `all substantially larger than the sectional area of pipe l2. rllhe air stream forced through the pipe is thereby diminished in intensity as it enters and passes through the collector and this results in less agitation ot the water, in more thorough cleansing 'of the air, and in more eliiective bathing 'ot the air stream so as to collect the water mist from the stream.

The flange 2l on baille 2O is perforated toV permit passage oi' water therethrough and thetunctioning oi the return bend 22 is thereby maintained.V

The arrangement and proportion el' the parts as illustrated. has been tested and found to be highly eliicient in removing dust vcollected by the blower, but obviously vari,-

ous modifications in the details of my collect-or be made without departing from the principles thereof, and l contemplate the exclusive use of such modiiicatioiis are included in the scope oit' my claims.v

l claim: Y vfl. in a dust collector, closed box having au opening in one side oit its top and an air inlet pipe extending through said box trom end to end and located near the opposite side ot' the box, a water holding depression-in the bottom of said box beneath said pipe, a conduit on said pipe leading into said depression, an upright longitudinal bail'lespaced slightly from the bottom of said. box and having a horizontal top flange below 'the top of the box and extending toward said pipe, a second upright longitudinal.

baille between said iirst mentioned bade and said top opening extending downwardly from the top oit said box and having a horizontallower flange above the bottom oit the box and extending toward said first inentioned battle.

2. in a dust collector, a closed box having an opening in one sidey of its top and an inlet pipe extending` through said box from end to end and located near the opposite side resaca? of the box, a wat-er holding depression in the bottom of said boxbeneatli said pipe, a conduit on .said pipe leading into said depression, an upright longitudinal baille spaced slightly from the bottom of said box and having a horizontal top flange be* low the top of the box and extending toward said pipe, a second upright longitudinal baille between said first mentioned baille and said top opening` extending downwardly from the t-op of said box and having a horilzontal lower flange above the bottom of the box and extending toward said .first men- L' Y l 4 .i 1 tioned baille, eacii ol said llanges having a return bend on its longitudinal edge 'or trapping water .in air striking against said flanges.

3. In aboli-like dust collector, a chamber for a body of water at one side occupying a relatively small portion oic the box space, an inclined iloor leading from the otherside oic the collector downwardly to saidchambei', there being a discharge opening in said collector at the side opposite saidchamber, an air intake conduit for conveying an air stream and discharging the same into; said chamber below the top thereof, the walls ot' the collector forming an air dischargepas-Y sage leading from above said chamber over saidA inclined floor, vertically extending and vertically staggered battles in said passage spaced above said floor for collecting water `from passingfrom sai d' chamber and fory discharging said collected water to said inclined iioor where it may llow bacli to said chamber. I Y f4 l. ln a dust collector, a chamber i'or a body of water, an air intake pipe extending through the collector from side to side above said chamber and adapted to be opened at either end, readily removable means for closing` the oppositeend of said pipe, a conduit from said pipe extendingfbelow theA top oit said chamber, a passageway for lair leading from the sides of said conduit to `the exterior ot the collector, and -baliles in said passageway for collecting water carried by the air stream moving `from said chamber te the exterior of the collector.v
